SLIDING DOOR Filed Oct. 4, 1938 Patented Feb. 13, 1940 2 Claims.

This invention relates to doors and more particularly to doors of a slidable type adapted to be moved between the walls of a dwelling or the like to provide a closure for the opening thereof.

The principal object'of the invention is to provide a door of this nature which will require less floor space than doors of a type which are swung on hinges, and to provide a door which is fairly simple in construction and operation.

The improved door consists of three members or parts co-acting one with the other, one of the members being designated as an operating member and the other members constituting the two leaves of the door which close and open a passageway to which the door is applied. The leaves of the door are nicely balanced'and pivoted to the operating member in such a manner that the leaves will move easily-one part of the leaves moving on a track and guided on the track by a co-acting pinion gear.

The invention may be readily understood from a perusal of the following detailed description,

taken in connection with the accompanying drawing, and in the drawing: Figure l is a side elevational view of the door in a closed position across a passageway of a building, the latter being sectioned and broken away Figure 2 is an edge view of the door taken from the left in Figure 1; Figure 3 is a view similar to that of Figure 1,

but showing the door in an open position; and.

Figure 4 is a detail view of one of the inner door facing pieces, cut to provide a recess to reapparent from the drawing, eXtends below the bottom edges of the leaves and projects through an opening I. in the floor 8, and is pivoted as at 9 to the underside of the floor. One edge of the foot as at I0 is cut to provide a slanting surface Charles 0. Coleman, Lamesa, Tex.

Application October 4, 1938, Serial No. 233,163

l5 to hold the door in a latched position. A pivot pin [6 pivotally connects the upper right-hand corners of the leaves and the operating member together so that when the door is moved. to an open position or closed position it swings freely on the pivotal points both at the top and bottom of the door structure.

For the purpose of providing a more easily rolling or sliding motion of the door there is provided a gear rack or track indicated at I! and a pinion gear l8. It will be clear from Figure 1.

that when the door is closed the slanting edges as at 4 of the door leave project beyond the operating member 5 and on these parts there is arranged the gear l8, the gear being carried on a pin l8a and adapted to be rotated between the leaves I and 2. The rack bar is fastened in an opening in the floor as shown.

The door leaves are held in their spaced parallel relation at one point by a strip of metal. l9

' with an opening as shown for the latch l4, previously described. The slanting edges of the.

leaves, as at 4, and their upper edges are held in spaced relation by pins 20, a notch 2l--a. being made in the operating member 5 to permit free movement at its upper end.

In Figurel one outer wall of the building is shown at 2! and the adjoining outer wall is not shown, revealing the inner wall 22 and the rack,

- bar I! is placed between the outer and inner walls. When the door is closed, one edge of the door abuts the door jam slightly beyond the door facing strip or'member A. When the door is open the opposite doorframe facing pieces B receive the door knob bar H in the recesses 0 provided therefor so that the door will be fully open. A recess D is also made in the operating member 5 to permit the door knob bar to move far enough without interference when the door is opened.

It is believed that the foregoing description will be sufficient for a clear understanding of the operation of the door without further explanation; It is .to be understood that the door is capable of being modified to a certain extent within the meaning of the invention and which may be said to come fairly within the scope of the claims appended hereto What isclaimed as new is:

1. A door of the class described comprising two leaves and an operating member, said leavesbeing spaced apart to receive the operating mem*- ber adapted to be slid therebetween, said leaves being pivoted to the operating member at one point and said operating member extending below the leaves and terminating in a foot, said foot projecting below the floor of the dwelling or the like to which the door is applied, and pivoted to said floor; the edges of said leaves at one edge being slanted from top to bottom of said leaves and projecting beyond one edge of said operating member; a gear mounted on said projecting parts of the leaves, a rack bar mounted in the floor, said gear adapted to ride on said rack bar when the door is slid open and closed.

2. A door of the class described comprising two leaves and an operating member, said leaves being spaced apart to receive the operating member adapted to be slid therebetween in the operation of the door, means for holding the leaves in spaced apart position, the leavesbeing pivoted to said operating member at the top of the door; said operating member extending below the bottom edges of the leaves and terminating in a foot, an opening in the floor to receive the foot, means for pivotally securing the foot to the floor; a latch carried by the leaves of the door, a bar supporting the latch, knobs carried on the bar, said bar being placed between the leaves of the door, a recess in one of the door frame facings to receive said latch; a toothed rack bar mounted in the floor, a pinion gear mounted between said leaves at one side of the door and adapted to ride in said toothed rack bar; a recess in said operating member to permit said bar carrying the knobs to move in the opening and closing of the door, and a recess in the door frame facing pieces to allow said bar knob to be received when the door is opened.
